News tagged with hydrogen fuel cell

Hydrogen is widely regarded as a promising and clean alternative energy source. The traditional source of hydrogen (H2) for fuel cell use is water, which is split into H2 and oxygen (O2). But O2 is a low-value product. So, ...

It's the worst short story ever written: on a dark and stormy night; the end. The real story—the context, the tension, and the motivations—are missing. That's what it feels like for scientists reading the reaction that ...

Researchers at the University of Illinois at Chicago have engineered a potentially game-changing solar cell that cheaply and efficiently converts atmospheric carbon dioxide directly into usable hydrocarbon fuel, using only ...

Scientists have looked for different ways to force hydrogen into a metallic state for decades. A metallic state of hydrogen is a holy grail for materials science because it could be used for superconductors, materials that ...

A team of scientists led by the Department of Energy's Oak Ridge National Laboratory has developed a novel way to produce two-dimensional nanosheets by separating bulk materials with nontoxic liquid nitrogen. The environmentally ...

(Phys.org)—Harvard Chemist Daniel Nocera has announced during a lecture at the Energy Policy Institute in Chicago, that he and his colleagues have engineered a bacterium that has made it capable of taking in carbon dioxide ...

(Phys.org)—Scientists have used sunlight to turn seawater (H2O) into hydrogen peroxide (H2O2), which can then be used in fuel cells to generate electricity. It is the first photocatalytic method of H2O2 production that ...

Hydrogen from the natural gas pipeline – a separation technique developed by TU Wien is opening up new possibilities for our natural gas network and improves the ecological balance of hydrogen fuel cells.
